Valley, as a degree of freedom, raises the valleytronics and classical analogs in fundamental and applied science. Here, by designing asymmetrical elastic metamaterials made of hard and soft materials, we present the valley anisotropy that has not been explored in conventional symmetric systems. We demonstrate the creation of valley topological insulators by tuning an anisotropic Berry curvature and show topological waves relying on operating frequencies. The proposed topological properties can contribute to better understanding the valley topology and to creating a different type of topological insulator.
